Research on the Application of Molecular Absorbers in Optics Camera Contamination Control

As a new type of contamination control technology, molecular absorber has the characteristics of convenient measuring, light weight, low power consumption, which is a useful way of controlling contamination of spacecraft optics camera. From the perspectives of on-orbit molecular contaminants and the characteristic of molecular absorber, this paper describes the sources and the characteristics of on-orbit molecular contaminants, analyzes the damages of contaminants and the effect on optics camera, and expounds the components and absorbing characteristic of molecular absorber, including adsorbent and base. Combined with the structure of optics camera, this paper proposes an application scheme of molecular absorber in the optics camera contamination control, and determines the future research trend.
